kIn Great Britain .lune 13, 1932 4 Claims. (Cl. 126-10) This inventionrelates to cooking 'ranges of the slow combustiontype incorporating athermal storage and hot-plate unit.

An object of thesinvention is to provide an improved construction invwhich said unit receives direct .heat from Vthe'iireand by contact withproducts of combustion flowing from the nre.

A further object off the: invention is to avoid leakage of heat fromsaid unit by conduction to Vthe range top.

Another object is to. provide an improved: construction ofoven designedto 'provide for an adequate supply of bottom heat .to the oven.

1 Other objects will appear from the following description. Y'

According to a primary feature of the invention the hot-platefconsttutedby. a massive metal plate is formed `with a deep depending wall ofmassive metal integral with or thermally in one with the hot-plateproper, said wall, when the hot plate is `in position, projecting intothe fire and being vspaced from the side of the re, to afford a passagebetweenwsaid wall and the side of the lire, the gases'of combustionowing up this passage and then below and in contact with the underside'of said plate, whereby said plate is heated by the gases in addition tothe heat transmitted thereto by said wall.

side with a rim orrlange forming the boundary of a space beneath the hotplate and open to Y said passage, said rim or flange resting on ahorizontal dividing plate spaced from the top of the oven. Y

In the accompanyingydrawings Fig. 1 is a plan, Fig. 2 a longitudinalsection and Fig. 3.a transverse section on the line II-II of Fig. 2showing a cooking range embodying the invention. Fig. 4 is a detailvertical section of part of the hot plate and of the top plate of therange, Fig. 5 is a similar view showing a modification. Fig. 6 is avertical section showing the arrangement of the panel and the grillingor toasting compartment.

According to the invention and as shown in the drawings the hot-plate 1constituted by a massive metal structure is formed with va deepdepending wall 2 of massive metal integral with the hot-plate proper,said wall 2 being insulated grate 5 and is spaced Vfrom a rebrick side6,

. as shown.

The hot-plate is also provided on its under-l TheV affording a clearpassage 7 for theupward flow of gases of combustion. The face ofthe'wall 2 nearer to the iirebrick side 6 is or may be ribbed Thehot-plate 1 is provided'on its I.underside with a depending rim orflange 8 formingthe Yboundary of a space 9 open to said passage '7.

' sulating material 22. The interior side wall 23 of the oven adjacentvto the vertical wall-15 is spaced from said wall 15 by insulation shownat 24. The opposite side wall 25 ofthe oven is integral with the topwall v12, being supported by the bottom plate 14 and bythe upper'edge ofthe interior side wall V23, a gap being provided betweenthe top vvall 12and themassive vertical W311115. l y

With the Ydescribed arrangement hot gases from the re Vflow upwardsthrough the passage '7, and past the upper portion ofthe wall 15, thestream of gases being sub-divided intoan upper and a lower stream ofwhichV the lower Vstreampasses along the top of the oven 13, downapassage 18 at the outermost side of the oven into a pocket 19 beneaththe oven, and thence upwardly by way of a passage 20 at the rear of the'oven to a ue outlet 16. The upper stream of gases passes into the space9 betweenk the underside of the hot plate 1 and the top of the dividingplate 11,

transferring its heat to the hot-plate 1, and passing thencealso to theiiue outlet 16 by way of a from the boundary Yedge of the aperture is aange or bracket 27 presenting an inwardly directed ledge 28. Projectinglaterally from the hot plate are lugs such as 29 penetrated byadjustable screws such as adapted to rest on the ledge 28, coniining thearea of metallic contact between the hot plate 1 and the range top 17say to three points only. The cavity between the range top `17'? and theledge 24 is filled with non-conducting vends of levelling screws ,30threaded into the ange portion 2'?? of the hot plate.` w

Forming part of one Wall of the fire chamber, say the front wall, is apanel 31 of thin reresisting material, such as fire-brick, carborundumor chromium steel, said'panel constituting a partition between the firechamber and a com- Y partment 32 embodied in the range and accessiblefrom the outside of the range, and serving as a radiant for use inbread-toasting or meat-grilling operations.

As is understood, the compartment 32 is sealed from theze chamber. Y
